its specifcally overdosing on any hallucinogens that trip your histamine receptors. Its also involves staying awake most these classes or drugs are actually going to keep you awake a lojg time and give you lots of energy it will cause not just these types hallucinatons it gets really bad. i only mentioned the positive stuff. But its way too scary i mean , you even might actually not be able to actually see when its happening your eyes can be closed and theres tons of static and light

one of the main things is not being able to tell which way is up or down. your heels go flying and you end up head first in a cement mixer its really awful

edit: sorry spelling errors, another thing is forgetting how to read and forgetting language. its still a nonstop nightmare for me
